Most buyers coming to us have already gone through a few supliers and know the headache of inconsistent purity—they're not looking for a sales pitch, they want something that actually holds up at >99.9% by HPLC, and we've got the COAs to back that up batch-to-batch.
It's a, CAS 2023788-19-2, and the molecular weight runs 4113.58 g/mol; storage at -20°C protected form light is non-negotiable or you'll see degradation in about 3-4 weeks, but we usually have stock ready to ship within 5-7 business days (check lead time for bulk orders over 50 vials).
The 10mg vial is the sweet spot for most researchers—basically, it's easier to reconstitute and dose than teh 5mg, and the 30mg tends to sit around longer than it should, so we see more repeat orders on the 10mg size.
We package 10, and what you get is sealed vials with individual lot numbers and a full COA; bulk pricing kicks in at 100 vials or so, and we've had buyers push it to 500 vials for multi-site studies, but that's a 2-3 week lead time minimum.
One thing that catches people off guard: the lyophilized cake can look slightly off-white depending on the batch—that's normal, not a purity issue, and it's not suited for anything outside research use, so don't expect it to pass a GMP audit without proper documentation.
